I MPROVED BOOT-TREE.-

TO ALL WHOM IT M AY CONCERN l Be it known that I, PETER DE'VRrEs, of. Adrian, in-'the lcounty of Lenawee, and State of Michigan, have` invented a new and-useful Improvement on Fine Boot-Trees; and I do hereby declare that the following is a:

full, clear, and exact description of the construction andl operation of thc'snme, reference being had to the annex-ed drawings, making a part of this specication, and to the letters of reference marked thereon, ,in which- Figure 1 is a side view. I Figure 2, a. sketch of the construction of the insidework. v Figure 3, a transverse section. The nature of my invention consists of a fine boot-tree, constructed with the foot B and front piece A', g.

`1, solid, and made in one piece without joint, and having'the footl '13, with the frontpiece A, back piece C, oi`

uniformthickness, say one and one-half inch thick, with the outer edges of the two latter rounded, the sides flat, as shown by the straight lines oZ e andfg in tlg. 3;v the toe dropped down, so as to leave the foot at an angle of about forty-five degrees, the bottom of the foot, from the ball a to the toe b, being nearly at across, the corners slightly rounded, and 'having the shank S hollowing. The tree is to be supplied with one or any con'- lvenient number of centre-spreadingkeys, K.

y It also consists of two spreading-screws, Gr und H, vtige. 1, 2, and, one oi' which, shown at G, g. 2, descends perpendicular-ly into the upper end of the front piece A, and strikes obliquely upon the back side of the metallic lever I, at the point t, and pressing it forward, throws the lower end of the elbow n against the spring vwhich is thereby pressed against the key K, and causes a spreading of the lower portion of the tree. I

The other spreading-screw, H, passes edgew'ise through the back piece C :It the top, and strikes directly against the top end of the key K, land causes a. spreading of the upper end of the tree. VThe whole is so constructed as to i't any sized boot. v

l Olzz'm.

What I cloim as my invention, and. desire to secure by Letters Patent, is-Y v The combination of the front andl foot A B, (made in onel piece,) the backC, the spreading-key K, the lever vI, elastic plate z', vertical screw G, and 'horizontal screw H, all arranged and employed in the manner and for the purposes set forth. l
